The strength of pushdown automata is increased by adding extra stacks. A PDA with two stacks has the same computation power as for a Turing Machine.

Splet14. okt. 2015 · However, the semantics are a bit different since DFAs/NFAs and PDAs always define total functions, while Turing machines (deterministic or non-deterministic) in general define partial functions. A partial function is one defined only on part of the domain. If f is not defined on x then we write f ( x) = ⊥.
